Import Tips

• Verify alloy composition certification showing high-nickel content (e.g

• >40% Ni) to confirm classification under 7306.40.50.05

• Measure and document wall thickness ≥1.65 mm and circular cross-section to avoid reclassification to thinner wall subheadings

• Obtain mill test reports (MTRs) proving stainless steel and welded construction; common pitfall is missing traceability docs
